No frills.....remodel job, framed for spa tub, sheet rocked except under framing, 20 GFI breaker protected seperate circuit, bonding to cold water pipe under framing but when I went under frame to do the bonding found copper pipe coming off of plastic water pipe. Am I bonding with this scenario? Must I go back to somewhere where the pipe is totally copper? BTW this is on the 16th floor of a high rise. doubt I could find any copper other than what comes out of the walls. This is a concern to me in Florida. Most water mains are PVC. This has probably been discussed before but I need to do this right and also to explain it to my apprentice. Thanks for your help, Tom

Was this a really dumb question or am I in the wrong Forum? I can find the answer without coming here but I thought it would make a good subject for others also. With the new format you have maybe I should have asked in the "Code" forum. Have a safe day all, Tom
